IMPROVEMENT I N'CO NNECTORS FOR BATTERY-CARBONS.

Specification forming part of Letters Patent No. 217,023, dated July 1, 1879; application filed March 29, 1879.

To all whom it may concern Be it known that 1, WILLIAM H. Ronenns, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Clamp-Conductors for Galvanic Batteries, of which the following is a specification.

Difiiculty has heretofore been experienced in connecting the carbonpoles of the galvanic battery in such a manner that there is no interruption to the current from imperfect contact with the carbon.

My invention relates to the combination, with a carbon pole of a battery and a yoke and screw, of an amalgam introduced between the carbon and the yoke, whereby an intimate contact between the clampconductor and the carbon is insured. v i

In the drawings, Figure l is a plan of the conductor and carbon, and Fig. 2 is a section of the same.

The carbon at is of any usual size or shape. b is a yoke-piece or stirrup, that is large enough to receive the end of the carbon within-it; and there is a clamping-screw, b, to apply the pressure to the carbon. Parts substantially like these, so far as described, have been used. Between the clamping-screw and the carbon I introduce a block of wood, 0, or similar slightly-yielding material, and the strip of platina-foil or other similar material, 6, which passes through a hole in c, so'that one end of the carbon.

1 also employ an amalgam between the yokeclamp and the carbon, such amalgam being preferably of mercury,upon a piece of German silver, soldered at i to the inner face of the clamp, so as to press firmly upon the car bon by the action of the screw.

The amalgam enters the pores of the surface of the carbon, and renders the contact of the clamp with the carbon very intimate.

I claim as my invention- In combination with the carbon pole of the battery and the yoke and screw, an. amalgam introduced between the carbon and the yoke, for the purposes and asset forth.
